What Is The Best Solar Tracker Motor?

This article is about choosing the best type of solar tracker motor. I wrote it for the Solar Power World “2013 Renewable Energy Handbook”.   Solar Tracker Motor & Drives When it comes to specifying electric motors for solar photovoltaic tracking applications, environmental protection is a prime consideration due to their exposure to the elements.

Some Brushless Motor Controller Alternatives for BLDC Motors Without Integrated Commutation Electronics

If you read yesterday’s post about when not to use a brushless motor with integrated commutation electronics, then it’s logical to want to know what kinds of alternatives exist. Fortunately, there are many. While in this post I’ll highlight a few that Dunkermotor produces, you should realize that many others exist as well. And, as […]

When You May Not Want to Use a Brushless Motor With Integrated Commutation Electronics

In an earlier post, I briefly described the features and benefits of brushless motors with integrated commutation electronics. Then I pointed out how easy it is to wire such a brushless motor compared to using separate components. However, now I want to outline some of the application characteristics that may indicate you should use separate, […]

Nissan LEAF EV and What is a Permanent Magnet AC Motor?

In my earlier post about the Nissan LEAF rare earth electric motor innovation, I promised to provide some more detail on the motor itself which is rather interesting. Car and Driver notes in its specifications rundown, “MOTOR TYPE: AC permanent-magnet synchronous electric motor, 107 hp, 207 lb-ft”. Of course, the vast majority of AC induction […]

New Nissan LEAF Rare Earth Electric Motor Innovation, Rare Earth Shortages and a Glass Half-Full

Yesterday, Popular Mechanics posted online the very topical story, “New Nissan LEAF Motor Cuts Rare Earth Element by 40 Percent“. What they’re talking about is reducing the amount of the rare earth, dysprosium, which is used to replace a small portion of the neodymium rare earth in Neodymium-iron-boron magnets in order to raise the coercivity […]

How to Wire a Brushless DC Motor with Integrated Commutation Electronics

Yesterday, I gave a brief explanation of just what is a brushless DC motor with integrated commutation electronics. While noting they represent a compact, simple good value motion solution, their ease of installation was recognized as another benefit. Today, I’ll show just how simple and easy it is to wire up a brushless DC motor […]

What is a Brushless DC Motor with Integrated Commutation Electronics?

A brushless DC motor with integrated commutation electronics will operate when nothing more than appropriate DC voltage is applied. Unlike conventional brushless DC (BLDC) motors that require connection to a separate driver/amplifier containing commutation logic those critical capabilities are built into the motor itself, thereby, making it much easier to wire and install in equipment. […]
